Configure the CData JDBC Driver for Highrise in a Connection Pool in Tomcat

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Highrise data from a connection pool in Tomcat.

Connect to Highrise Data through a Connection Pool in Tomcat

1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
2. Add a definition of the resource to the context. Specify the JDBC URL here.

   Highrise uses the OAuth authentication standard. To authenticate to Highrise, obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with Highrise. You will also need to set the AccountId to connect to data.

   See the "Getting Started" section in the help documentation for a guide to using OAuth.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Highrise JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.highrise.jar
   

   Fill in the connection properties and copy the connection string to the clipboard.

   You can see the JDBC URL specified in the resource definition below.

   <Resource name="jdbc/highrise" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.highrise.HighriseDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:highrise:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost;AccountId=MyAccountId;InitiateOAuth=GETANDREFRESH;" maxActive="20" maxIdle="10" maxWait="-1" />
   

   To allow a single application to access Highrise data, add the code above to the context.xml in the application's META-INF directory.

   For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Highrise for all applications.

3. Add a reference to the resource to the web.xml for the application.

    Highrise data JSP
    jdbc/Highrise
    javax.sql.DataSource
    Container
   
   

4. Initialize connections from the connection pool:

   Context initContext = new InitialContext();
   Context envContext = (Context)initContext.lookup("java:/comp/env");
   DataSource ds = (DataSource)envContext.lookup("jdbc/Highrise");
   Connection conn = ds.getConnection();
